I

For controlling the clutch 1-1, a reel: 'sh-ait 1% extends along theouterside of the hous ing'IO-end is provided with a clutch shifting:fork 15, and alseW-ith u lever 16fhy' means of which the shaft may heturned by hand to either eiiga-ge or disengage-the clutch; Obvi eusly,when the clutch is thrown in, the feed tolls-6 and 7 will bedriventofeed the stfips of cloth 1? through the machine,

whereas when the clutch is thrown out,- sr'id 7 ti-velji, said cranksbein formed Wit-h rod 2 guides 21 and 21: tltreugh which vetti'zil rods22 and 22 pass slidablyi' The upper ends oftl-iese rodsai'epivoted tocrEinks QS and 23* on theends of aniaster rock sliaft 24v hieh eiitend'sacross the housing above I the roller 9: Pluses and 25 pass throug-l'i'the rods- 22' and 22 respectively, over the guides 21' and 21 andcoiled; compression springs 26 and 26 are interposed between said pinsand guides. By this construction or some equivalent Iarrangelnent,oneuvay connections are provided between the 2020 and the rods 2222;Thus, the arm 20' may force upwardly on the rod 22 totu'rn the shaft24-,vvithout any correspond ing movement of the arm 207*"2md viceversa'. It will thus be seen that if a snail or the like engages theguide 18, this guide Will be swung upwardly, tlireby turning the rockshaft 19- and swinging the arm 20 to" till raise the rod 22, causing thelatter to act on the crank 23 and turn the shaft it. Similarly, if aknot or the like on a strip of the cloth comes in contact with the guide'18, the rock shaft 19 will be turned, causing crank 20 to forceupnuirdly on rod 22, thus causing crank 23 to turn the rock shaft 2%.Provision made for transmitting motion from this master rocl; shaftfl i,to the clutch throw out shaft 1 1, so that 1novcment of said mastershaft under the lifting motion of either of the guides 1S--18, willautomatically throw out the clutch and stop the machine.

In the present showing, the arm 93 connected by a vertical wt 2?, withan arm 28, the latter being secured to and projecting inwardly from theshaft 14;. Thus, each time the shaft 2a is turned by one or the other ofthe guides 1S-.l8 rod :is lifted, causing the arm 28 to turn the shaft1%, thereby throwing the clutch 11 out. For a purpose to appearhereinafter, certain details are preferably used in connection with theupper and lower ends of the rod 27. The upper end of this rod isconnected by a universal joint or the lilce ill) with the arm 23, whilethe lower portion of said rod is receivable in either of a pair of hooks30 on the arm 28, said rod being provided with a shoulder 31 under thisarm. it is the engagement of this shoulder with the arm, up on liftingof the rod 27, which arises said arm to swing upwardly,thereby turningthe shaft 14. The hooks 30, it will be observed, are different distancesfrom the shaft 14. Thus, when the rod is engaged with one, the turningmovement imparted to said shaft 14, will be greater than when the rod isengaged with the other. The detachable connection between the rod andarm, at forded by these hooks, also possesses another advantage whichwill be hereinafter fully explained.

Very often, minor knots or snarls on the strips 17, pass through theguides 18-18 without actuating the stop motion for the machine.Auxiliary means are hence provided to be encountered by such minorimperfections, to bring the machine to a standstill. 111 the pre entembodiment of the invention, the shaft 24 is provided with laterallyl'n'ojccting arms 32 carrying a. curved shoe 33 suistantially arcuate incross section and which extends transversely of the paths of thestrip-F; T but is normally supported out of contact with said strips,due to the provision of an adjustable stop 3i, upon which the arm 23 ofthe roclt shaft 21, nori'nally rests, as shown in Figs. .land 5. Thus,while there is no dragging ol the shoe 33 upon the strips 17, any snarlor the like which passes through the guide 18 or 18, will engage andlift said shoe. causing rcele ing of the shaft 24: and pulling of therod 2? to turn the shaft 121; and disengage the clutch ii. The shoe 33being of shell-like structure and made of comparatively thin material isof trivial weight compared to the weight of a roller performing asimilar function and heretofore comi'nonly used and hence is freelyswingable. Hence, less strain is placed upon any strip of cloth whichmust necessarily raise said shoe. At this point, attention may also bedirected to the fact that whena knot or the like on any strip engagesthe guide 18 or 18", the strip must only raise the guide which itengages, so that here again, the weight necessarily raised by the strip,is considerably less than that which must be -aised by falling machineshaving the common stop motions. i

ll hen initially engaging the strips 17 with the machine, it isadvisable to support the shoe 33 in an elevated position. This can bedone by disengaging the rod 27 from the arm 28 and pushing upwardly uponsaid rod, thus causing the c 'ank 23 to turn the rock shaft 24-, whichcarries said shoe 33. The rod 2? may then be supported tem porarily uponan appropriate ledge 35, projecting from the housing 10, this ledgebeing shown in Figs. 1, 2 and 4.

In actual practice, excellent results have been obtained from thegeneral construction herein disclosed. 'lhcrcfore, such construction ispreferably followed. However, within the scope of the invention asclaimed, variations may of course be made.

I claim: 1 i

1. In a cloth-handling machine, clothfeeding means having a clutch, arock shaft for disoi'igaging said clutch, an arm secured to andprojecting laterally from said rock shaft, a master rock shafttransverse to the cloth path and having a lateral shoe adapted to beengaged by a snarl to turn said master rock shaft, a crank on saidmaster rock shaft, a rod connecting said crank and said arm anddetachably connected with the latter, and means for holding said rod inan abnormal position when disconnected from said arm, said shoe beingthen spaced from the cloth path.

2. In a cloth-falling machine, cloth-feeding means, guides for aplurality of cloth strips, means mount-in said guides for independentmovement, a rock shaft spaced from said guides and disposed transverseto the paths of the cloth strips, one-Way operating connections betweensaid guides and said rock shafts permitting movement of any one ofsaidguides to turn said rock shaft, means connected with said rock shaftfor stopping the feeding means when said shaft is turned, and laterallyprojecting strip-cngaging means on said rock shaft adapted to be engagedby a snarl to turn said shaft in the same direction in which it isturned by any of said guides.

3. Ina cloth-fulling machine, cloth-feeding means, guides for aplurality of cloth strips, means mounting said guides for independentmovement, permitting movement of any one guide by a snarl of the clothstrip guided thereby, arock shaft spaced from said guides, one-Wayoperating connections between said guides and said rock shaft permittingmovement of any one of said guides to turn said rock shaft, meansconnected with said rock shaft for stopping said feeding means when therock shaft is turned, said rock shaft being transverse to the paths ofthe cloth strips and having laterally projecting strip-engaging" meansadapted when engaged by a snarl to turn said rock shaft in the directionin which it is turned by any of the guides, and stop means limiting theturning of the rockshaft in one direction to prevent said strip-engagelng means from dragging on the cloth under normal circumstances.

4. In a cloth-fulling machine, cloth-feeding means, guides for aplurality of cloth strips, independent axially alined rock .lng meansbetween said rods and the cranks of the other set forming one Waydriving connections between the latter and sald'rods and permittingturning of the master rock shaft by turning of any of the independent 7rock shafts, and stopping means for the aforesaid feeding meansoperatively connected with said master rock shaft and actuated byturning thereof.
